In recent years there has been a growing interest in examining the various blood cell stages and their possible role in the immune and physiological stress response in fish. Cadmium is a well-known industrial and environmental contaminant and in a recent report of cadmium (4-36 ..mu..g Cd/L) effects on blood and other tissues in rainbow trout (Salmo gairdneri), it was found that short-term exposure caused significant reduction in tissue glycogen levels while long-term exposure increased the size of the hemopoietic tissue, the liver. In this study the spleen somatic index, total and differential erythrocyte and leucocyte counts in cadmium-exposed rainbow trout were measured. The lower working concentrations include levels (1.5-6.3 ..mu..g Cd/L) recommended by the USEPA (1980) for protection of freshwater aquatic life.
